Ok very quick, i did new voices to a new race i created and added them as FUZ files... they works fine when the mod files are loose or Packes as a BSA with no compression, but as soon as i BSA the files with compression enabled it Crash the game when the audio file is about to be played, the mod is rather large and would help a lot if it were to be compressed, so what is the whole deal? can some provide any assistance?

Archive.exe doesn't compress certain things past certain sizes properly. Use BSAOpt instead, it's faster, more efficient, and doesn't cause these issues.
